Anders Behring Breivik, responsible for the killing of 77 people in Norway four months ago, may escape prison, it has been revealed. The gunman set off a car bomb in Oslo, killing eight people, before heading to the island of Utoeya disguised as a policeman, where he shot dead 69 teenagers.

Behring Breivik has been assessed by psychiatrists, who have concluded that Breivik was insane at the time of the murders. Norwegian website VG stated that Mr Breivik was suffering from “psychosis”, a condition which changed his mental state and dramatically affected his judgement.

This report, which was presented to the Oslo district court this morning, still needs to be examined by a medical commission in order to make sure it meets the professional criteria required. However, if it is accepted as a viable experts’ opinion it could mean that Behring Breivik could not be sentenced to a prison term, but would instead be transferred to a mental institution, where he would undergo psychiatric treatment.
